Beit known that-I, -HENRY KIMME'rfa citizen .ofthe United States,residing at Kansas/City, in thecounty of Jackson 'and State of Missouri,have invented certain new,V and useful Improvements in Vehicle- B'akes';and Idodeclare the following to be alfiill,clear,` andexactdescriptionfof the invention, Such'as'willenabl others skilled in:thefartl ,to f which fit: vappertainsI to make andusethe same, referencebeing had to the afeconipanying drawings, and to the vletters andfgu"@ofA reference marked thereon,

which fi'iii a 'part of this specification.v

This invention relates to rnotor vehicle brakesfand particularly to a'service' brake Wbdimey be 'readily appled'fo an.. existing typf'riinotorfvehiolesasj an attachment without materially altering thechassis of thel fvehicle and Wheh may, if' desired, be applied as anraugmenting medium` to take partof the lbraking load of the brake fur;

nishedfby the manufacturer as part of the standard equipment ofthevehicle. f y11;.Whilefthe braking' fechanismf kis adapted be builtin aspart of the original equipinent'of the motor vehicle, it isnqtjespecially intended to be`subs'tituted for those servicebrakingmechanismsfwhicli operate through theftrahslnission. Forjexample, the ordinai'yfFord transmission is provided with a brakebandadapted to retard the rotation of thel'drive'shaft of the transmission;that is, the braking force is transmitted through the drivejshaftadjacent to the engine, through thet'ransInission andy tothe rea-rwheels. In abtualpractioe, it has been found that the Y i applcationofsuch ,a brake to va heavily loaded truck on a downgrade causes theentire inertiaof'the loadto be ,applied through the transmission so thatparts o f the transmissionaresubjected-to severe shocks and wrenchingstrains causing chatter and otherwise deteriorately affecting theltrans,- mission.

My invention contemplates-the provision l V of'means Whereby'a moreeffective braking Y VEHICLE-BRAKE.
